Section 27-719
§ 27-719 General. The applicable provisions of article seven of
subchapter one of this chapter shall apply.
Section 27-720
§ 27-720 Boring and test pit operations. Boring and test pit
operations shall be subject to controlled inspection, except that fifty
per cent or less of the required number of borings and/or test pits may
be inspected by an architect or engineer other than the architect or
engineer designated for controlled inspection. The records of borings
and/or test pits shall be attested to as follows:
(a) The architect or engineer shall file a report stating which
borings and/or test pits were performed under his or her inspection and
whether such inspection was performed personally or otherwise. If the
inspection was not made personally by the architect or engineer, the
name and address of the inspector shall be noted. It shall be stated:
that the borings and/or test pits so inspected were made and were
carried to the depths indicated; that, to the best of the architect's or
engineer's knowledge and belief, the description and classification of
the soils are a true description of the samples recovered from the
respective borings and/or test pits; that such samples were recovered at
the levels indicated; and that the boring and/or test pit work
progressed in such manner that the samples recovered are reasonably
representative of the subsurface conditions.
(b) The accuracy of the other data indicated on the boring records
shall be attested to by the drilling contractor or by the driller making
the borings.
Section 27-721
§ 27-721 Piling. The installation of all piling shall be subject to
controlled inspection. Such inspection shall be performed only by an
architect or engineer resident at the site, except that where more than
one pile rig is working at a site, inspection of the work may be
performed by nonlicensed or nonregistered personnel working under the
resident architect or engineer, who need act only in a supervisory
capacity. This exception shall not apply, however, in the cases of
timber or steel piles driven to end bearing as described in article ten
of this subchapter. Materials for piling shall be subject to inspection
requirements as prescribed in subchapter ten of this chapter for those
or like materials. In all cases, an inspector shall be assigned to
observe the operations of each rig.
Section 27-722
§ 27-722 Footings, foundation piers, foundation walls and pile caps.
The provisions of section 27-683 of article six of this subchapter shall
apply.
Section 27-723
§ 27-723 Subgrade for footings, foundation piers, and foundation
walls. The soil material directly underlying footings, foundation
piers, and foundation walls shall be inspected by an architect or
engineer after excavation and immediately prior to construction of the
footings. If such inspection indicates that the soil conditions do not
conform to those assumed for purposes of design and described on the
plans, or are unsatisfactory due to disturbance, then additional
excavation, reduction in allowable bearing pressure, or other remedial
measures shall be adopted, as required. A copy of a report or reports on
such inspection or inspections describing the conditions found and any
necessary modification of the design, and bearing the signature of the
architect or engineer making the inspections, shall be filed with the
commissioner. In addition, notification shall be received by the
department at least two working days prior to construction of the
footing, pier, or foundation walls, that the subgrade is ready for
inspection unless the requirements of section 27-209 of article
twenty-one of subchapter one of this chapter have been met.
Section 27-724
§ 27-724 Construction required for or affecting the support of
adjacent properties or buildings. Except in cases where a proposed
excavation will extend less than ten feet below the legally established
grade, all underpinning operations and the construction and excavation
of temporary or permanent cofferdams, caissons, braced excavated
surfaces, or other constructions or excavations required for or
affecting the support of adjacent properties or buildings shall be
subject to controlled inspection. The details of underpinning,
cofferdams, caissons, bracing, or other constructions required for the
support of adjacent properties or buildings shall be shown on the plans
or prepared in the form of shop or detail drawings and shall be approved
by the architect or engineer who prepared the plans.
